No causal effects of serum urate levels on the risk of chronic kidney disease: A Mendelian randomization study

Background Studies have shown strong positive associations between serum urate (SU) levels and chronic kidney disease (CKD) risk; however, whether the relation is causal remains uncertain. We evaluate whether genetic data are consistent with a causal impact of SU level on the risk of CKD and estimated glomerular filtration rate (eGFR). Methods and findings We used Mendelian randomization (MR) methods to evaluate the presence of a causal effect....
